  摘要：

  开发了 Cu(OAc)2 催化的 2-(1-炔基) 苯并二亚胺与水的串联反应，用于合成异喹啉-1(2H)-酮。此外，只需在反应体系中加入 N-卤代琥珀酰亚胺（NXS：X = Cl、Br、I），即可以良好的收率获得 4-卤素取代的异喹啉-1(2H)-酮。机理研究表明，该反应可能是由 2-(1-炔基) 苯扎二亚胺的高度区域选择性分子内环化引发的，生成相应的异喹啉鎓中间体。

• Palladium(0)-Catalyzed Regioselective and Multicomponent Synthesis of 1,2,3-Trisubstituted 1<i>H</i>-Indenes
  作者：Hirokazu Tsukamoto、Tatsuhiko Ueno、Yoshinori Kondo

  DOI：10.1021/ol071107v

  日期：2007.8.1

  synthesis of biologically important indenes bearing three substituent groups at the 1-, 2-, and 3-positions from available o-ethynylbenzaldehyde derivatives and organoboron reagents under palladium(0) catalysis is described. A two-component coupling reaction in methanol provides 1H-indenols, whereas a three-component reaction involving secondary aliphatic amines as the third component in DMF affords 1H-indenamines

  描述了在钯（0）催化下由可用的邻乙炔基苯甲醛衍生物和有机硼试剂对在1、2和3位带有三个取代基的重要生物茚进行多组分合成。在甲醇中的两组分偶联反应可提供1H-茚满，而在DMF中将脂族仲胺作为第三组分的三组分反应可提供1H-茚满胺。该方法允许组合制备非对称取代的1H-茚，而这不能通过先前的合成途径制备。

  method for 1,2-dihydroisoquinolines via the 6-endo-dig cyclization of 2-alkynylaldimines and nucleophilic addition has been developed. When the 2-alkynylaldimines were reacted with various nucleophiles such as nitromethane, dimethyl malonate, phenylacetylene, hydrosilane, allylstannane, and ketene silyl acetal in the presence of a rhenium catalyst, the corresponding 1,2-dihydroisoquinolines were obtained

  rhenium-catalyzed synthetic method of 1,2-dihydroisoquinolines and isoquinolines has been developed. When the 2-alkynylarylaldimines were reacted with various pronucleophiles, such as nitromethane, dimethyl malonate, and phenylacetylene, in the presence of a rhenium catalyst, cyclization and subsequent nucleophilic addition proceeded to give the corresponding 1,2-dihydroisoquinolines in moderate to good yields

  开发了一种铼催化合成1,2-二氢异喹啉和异喹啉的方法。当2-炔基芳基醛亚胺与各种亲核试剂（例如硝基甲烷、丙二酸二甲酯和苯乙炔）在铼催化剂存在下反应时，发生环化和随后的亲核加成，以中等至良好的收率得到相应的1,2-二氢异喹啉。当使用氢硅烷、烯丙基锡烷和烯酮甲硅烷基缩醛代替亲核试剂时，氢化物、烯丙基和-C(CH)COOCH基团被引入到1,2-二氢异喹啉的1位上。 1,2-二氢异喹啉也可通过铼催化的 2-炔基苄胺环化合成。异喹啉的合成是通过使用-丁基-2-炔基醛亚胺来实现的，该亚胺是通过2-炔基苯甲醛和-丁胺的反应制备的。
• Highly Selective Construction of Medium-Sized Lactams by Palladium-Catalyzed Intramolecular Hydroaminocarbonylation of Aminoalkynes
  作者：Yue Hu、Hanmin Huang

  DOI：10.1021/acs.orglett.7b02284

  日期：2017.10.6

  A novel palladium-catalyzed intramolecular hydro-aminocarbonylation of aminoalkynes has been developed. This direct and operationally simple protocol provides a rapid and reliable approach to a diverse array of valuable seven- and eight-membered lactams with high chemoselectivity and regioselectivity. The high selectivity might be attributed to rational tuning the electronic nature of the amine moiety and the palladium catalyst, which enabled this transformation to proceed in the absence of acidic or any other additives under fairly mild reaction conditions. This method paves the way for the synthesis of medium-sized lactams.

  A silver(I)-catalyzed reaction of 2-alkynylaryl aldimine with trimethyl(trifluoromethyl)silane is reported. This reaction proceeds efficiently under extremely mild conditions to generate 1-(trifluoromethyl)-1,2-dihydroisoquinolines in good yields. A three-component reaction of 2-alkynylbenzaldehyde, amine, with trimethyl(trifluoromethyl)silane is presented as well. (C) 2013 Elsevier Ltd. All rights reserved.
